depending on how serious you are. learning from the people who build your vehicle= less time and probably net you better results than researching it all yourself then go through months and years of trial and error. most of the real good spl guys been doing it for 5 years or more on a serious level so they already been through the trial and error already. usually on a cost effective approach if you scrap 2 or 3 systems to finally get what you want you probably already would have spent the same amount as you would have getting it done right to begin with. basically why waste time to research when you can see all your research unfold in your car. most installers are glad to explain things as long as the car's owner isnt a retard about things lol there is nothing wrong with wanting a job done right but there is also come to a degree of understanding what needs to be done inwhich to achieve the results you want
